The present invention relates to improvements 1n Vcultivating' implements and has partlcular'reference to a combination plow and cultivator. It is particularly proposed,V

in the present invention, to provide a cultivator attachment for a multiple gang plow in such a manner that the cultivator attachment is directly fixed to the gang plow, after the plow shares have been removed, so that the whole implement then becomes a cultivator arranged to be manipulated'in the same manner as the gang plow. The ordinaryy gang plow, as now commonly used for cultivation of large acreage, includes a plurality of longitudinal frame members fixed t0 one another and arranged in parallel relation and supported relative to a pair of wheels in such a manner that the position of the frame relative to the wheels can. be adjusted by means of a lever arrangement for the purpose of adjusting the depth to which the land is to be plowed. My cultivator attachment is particularly designed to be secured directly to the longitudinal frame members of the plow after the plow shares have been removed, so that the cultivator thereafter enjoys all the advantages of the gang plow. Further objects and advantages of my invention will appear as the specification proceeds. Y

The preferred form of the invention is illustrated in the accompanying drawing` in which Figure l shows a top plan view of a three gang plowhaving m cultivator attachment secured thereto, with the lever arrangement omitted for the sake of clearness and Figure 2 a side view of the same arrangement. `While Ifhave shown only the preferred form of the invention, it should be understood that various changes or modications may be made within the scope of the claims hereto attachedwithout departing from the spirit of the invention.

The three longitudinal frame membersV l,

2 and 3 are held in fixed and parallel relation to one another by means of suitable braces 4 andare supported on the wheels 5. A suitable lever arrangement, well known in the art and not shown in the drawing, is used to adjust the relative height and p osition of the frame members as compared with the wheels. Of the three members, the second one is longer than the first one and extends further rearwardly, and the third one is longer than the second one, extending still further rearwardly. The three frame membersare bent downwardly to terminate in stumps 6 adapted to have the nioldboards for the plow shares attached thereto by means of bolts extending through the perfor-ations 7. i

My invention consists in the cultivator attachment which comprises iny its principaly l features the two transverse'bars 8 and 9 Joined attheir ends by the bars ll and secured to thelongitudinal members 2 kand 3 in such a manner as to lie flat on top of the plow in transverse relation thereto. The bar SV has a plurality of standards ,secured thereto as shown at 12, standards extending rearwardly through a certain distance and then bent downwardly so that the cultivating tools 13 secured to the extremities thereof are in operative engagementV with the ground surface. Intermediate portions of the standards are secured to the second transverse bar 9 by means of U-shaped clamps 14 i straddling the standards and extendino' into the bar 9 and held in. place by means of nuts 16. The two bars 8 and 9 are fastened to the'longitudinal frame members by means of clamps 10. bars S, 9 and 11 is secured to the longitudinal frame members l and 2 by the braces 17 leading from the forward edges ofthe frame to the front ends of the members l and 2,

vand a yoke shaped member 2O is stretchedover the bar 9 for reinforcing the latter. Vthere the cultivating teeth are in line with the stumps of the plow frame, the latter may be used for supporting a cultivating tool as shown at l8. y The advantages of my attachment are ap-l parent. lt allows a multiple gang plow to be changed into a cultivating implement in a very short Vperiod oftime. All that is necessary is to remove the moldboards from the stumps of the plow frame and tosecure the cultivator attachment by placing the same on top of the longitudinal frame members and then fastening it in place by means ofthe clamps l0 and the braces 17. The

may be raisedV and lowered by means of. the

The frame formed of the'Y regular lever arrangement not shown in the j f drawing.

Iclaim: A

An attachment for a multiple Ygang plow having vertically adjustable parallel frame i members comprising a transverse bar rig- Y idly andfdetachably secured to one of the Y frame members and movable vertically therewith, standards of dierent lengths rigidly secured'to saidf'bar and extending rearwardly therefrom forv diHerent distances and bent downwardly for operative engagement wlth the ground surface and a second bar secured to the said frame member rearwardly of the first bar and in parallel relationV thereto, said second bar being rigidly secured to the'rearwardly extending portion of the said standards, and a yoke extending across the second bar for reinforcing the Same.
